Very simple 1841 PPPoE config

I'm trying to get a PPPoE config working on an 1841.  Running c1841-advsecurityk9-mz.124-3i.bin . I tried c1841-advsecurityk9-mz.151-4.M4.bin but it has even less protocol options.

I used a walkthrough but it suggests the following fragment which doesn't work because there is no "protocol ppoe" command available on my system.  Perhaps there is a simpler way to do this?  I tried c1841-broadband-mz.151-4.M4.bin but it doesn't seem to have ssh available.

vpdn enable
vpdn-group 1
request-dialin
protocol pppoe
exit

My config looks something like this:

version 12.4

service timestamps log datetime msec localtime show-timezone
service password-encryption
service compress-config

Re: Very simple 1841 PPPoE config

Hello Kim,

The VPDN configuration is not relevant to what you are trying to accomplish. Please remove all VPDN-related commands, i.e.:

no vpdn-group 1

no vpdn enable

What you are currently missing in the configuration you posted is a simple line on the FastEthernet0/0 interface:

pppoe-client dial-pool-number 1

Adding this line should successfully start the PPPoE client and tie its operation to the Dialer1 interface.

Also, please remove the  ppp authentication chap pap callin line from your Di1 interface - it is again not relevant to your configuration. The authentification will still work successfully but this command is used to perform an authentication in the reversed direction during callbacks - clearly not your case here.

Best regards,

Peter
